'97 into '94 4L60e (Codes as well)
The speedo is WAY off.I might be going 20 but it shows like 70mph. Also it feels like the car is starting in 2nd or 3rd gear instead of 1st of course.
Here is a list of codes I have as well:
53 for high system voltage
59 for tranny fluid temp sensor circuit high - low temp
81 for QDM or shift B solenoid fault
Thanks!
94 was different from 95 due to some internal changes.
And 96-97 were quite different because of the switch to OBD2.
So I will do what I didn't want which is remove the 97 tranny and install a 94.
Well, how much would the 97 tranny go for since I will just have to sell it? It's a new transmission from the chevy house here.
